Create an event

If you do not find a suitable existing event, you can create your own.

Before you begin

Role required: admin

About this task

The gs.EventQueue function works directly with the backend and therefore business rules that are called by gs.EventQueue() are not invoked.


  1. Navigate to System Policy > Events > Registry.
  2. Click New and fill in the form.
  3. Click the Business Rules related link.
  4. If you are creating an event for a base system table, select the existing event business rule for the table.
    For example, select the sc request events business rule to create a custom Request event.
  5. If you are updating an existing event business rule, add a new condition to the Script.
    The following sample script adds a request.commented event with the user's Sys ID as parm1 and the user's user name for parm2.
    if (current.operation() != 'insert' && current.comments.changes()) {
    gs.eventQueue('request.commented', current, gs.getUserID(), gs.getUserName());
  6. If you are creating an event for a custom table, create a new business rule that runs after database operations.
    For example, this business rule defines several events for a custom application called Marketing Events.
    Table 1. Sample event business rule
    Field Value
    Name Attendee Events
    Table Attendee [x_snc_marketing_ev_attendee]
    Application Marketing Events
    Advanced Selected
    When after
    Insert Selected
    Update Selected
    Delete Selected
    Add custom script that:
    • Checks for one or more conditions on the current record.
    • Calls the gs.eventQueue() method and specifies an event name.

    See code sample.

    Note: If you add Filter Conditions, Role conditions, or a Condition value, verify it runs the business rule when expected.
    (function executeRule(current, previous /*null when async*/) {
       //This function will be automatically called when this rule is processed.
            //Add event when attendee inserted
            if(current.operation() == 'insert' && current.marketing_event.changes()) {
                    gs.eventQueue('x_snc_marketing_ev.attendee.added', current,
            //Add event when marketing event changes
            if(current.operation() == 'update' && current.marketing_event.changes()) {
                    gs.eventQueue('x_snc_marketing_ev.attendee.deleted', previous,
                    gs.eventQueue('x_snc_marketing_ev.attendee.added', current,
            //Add event when attendee deleted
            if(current.operation() == 'delete') {
                    gs.eventQueue('x_snc_marketing_ev.attendee.deleted', current,
    })(current, previous);
  7. Register the event.

What to do next

Create a script action or notification to process the event.
